The antifouling paint can effectively delay the adhesion of marine organisms, and the organotin (TBT) has a broad-spectrum bactericidal effect, but the organotin self-polishing antifouling paint system can generate side effects on the environment and is forbidden to use.
The current self-polishing antifouling paint without organic tin has three main types: the antifouling paint using copper acrylate polymer, zinc acrylate polymer and silane acrylate polymer as base material has antifouling period of about 2 years. The Chinese patent publication No. CN101550305A discloses a long-acting self-polishing antifouling paint, which mainly comprises copper acrylate resin and a composite organic antifouling agent, is suitable for being used as an antifouling paint at the bottom of a ship, and can effectively prevent marine organisms from fouling the bottom of the ship within 3-5 years.
The cooling seawater circulating pipeline of the nuclear power station is soaked in seawater all the year round and cannot move like a ship, so that marine organism pollution is easier and more serious, and no long-acting antifouling paint specially used for the cooling seawater circulating pipeline of the nuclear power station exists at present, so that the invention is provided.
Disclosure of Invention
The invention aims to provide an antifouling paint which has long antifouling life and is particularly suitable for long-term effective antifouling of a cooling seawater circulating pipeline of a nuclear power station.
The antifouling paint is soaked in seawater for a long time in the using process, and long-acting antifouling is required to reach 5 years, so how to effectively control the long-time and uniform release of toxin and control the thinning rate of an antifouling paint coating are important, and the effect can be achieved after the components are matched with each other when the paint formula is designed.

Rosin resin is an important slow water-soluble resin raw material, cuprous oxide is a toxicity factor, the dissolution rate of the rosin resin in the formula is the guarantee and the key of the antifouling life of the antifouling paint, and factors influencing the dissolution rate have the interaction between the components of the whole paint system and the chemical components in seawater besides the interaction between the solvent and the rosin resin. The liquid rosin resin and the chlorinated rubber resin are selected as main carriers of the cuprous oxide in the formula, and the nano calcium carbonate and the xylene-containing solvent are used as auxiliary materials, so that the resin can be uniformly hydrolyzed to drive the cuprous oxide to be slowly released, the cuprous oxide is not dissolved in seawater too fast or too slowly in service, and the long-acting antifouling effect is achieved. The nanometer calcium carbonate can reduce the free energy of the surface of paint and make the surface of paint smooth.
As one preferable scheme, in the antifouling paint, the components are used according to the parts by weight:
in one preferable embodiment, the solvent in the antifouling paint is xylene and a modified rosin-based polyoxyethylene solution. The modified rosin-based polyoxyethylene liquid is a rosin polyoxyethylene derivative nonionic surfactant prepared by reacting rosin and polyoxyethylene, and when the modified rosin-based polyoxyethylene liquid is used in the formula disclosed by the invention, the modified rosin-based polyoxyethylene liquid can play a better role in regulating the dissolution speed of resin, and the antifouling life can be effectively prolonged to 5 years.
More preferably, in the antifouling paint, the modified rosin-based polyoxyethylene solution accounts for 2-3 parts of the total mass of the antifouling paint.
The invention also provides a preparation method of the antifouling paint, which comprises the steps of mixing the liquid rosin resin, the chlorinated rubber resin liquid, the iron oxide red, the nano calcium carbonate, the cuprous oxide, the titanium dioxide and part of the solvent, dispersing uniformly, and then placing the mixture into a grinding machine to be ground to the fineness of below 40 mu m to form pre-refining slurry; placing the pre-refining slurry in a clean stirring kettle, sequentially adding a dispersing auxiliary agent, a defoaming agent, a dustproof auxiliary agent and the residual solvent under the stirring condition, uniformly mixing and stirring until the fineness is below 40 mu m; and (5) filtering and packaging.
The invention also provides application of any one of the antifouling paint in antifouling of a cooling seawater circulating pipeline of a nuclear power station.

EXAMPLE 1 antifouling paint preparation
TABLE 1 Long-term antifouling paint formulation
Please supplement the formulations for the two test coatings.
The preparation method comprises the following steps:
the solvent consists of dimethylbenzene and modified rosin-based polyoxyethylene liquid. Firstly, mixing liquid rosin resin, chlorinated rubber resin liquid, iron oxide red, nano calcium carbonate, cuprous oxide, titanium dioxide and part of solvent, uniformly dispersing, and then placing the mixture into a grinding machine to grind the mixture until the fineness is below 40 mu m to obtain pre-refining slurry; placing the pre-refining slurry in a clean stirring kettle, sequentially adding a dispersing auxiliary agent, a defoaming agent, a dustproof auxiliary agent and the residual solvent under the stirring condition, uniformly mixing and stirring until the fineness is below 40 mu m; and (5) filtering and packaging.
Example 2 product Performance testing
The antifouling paints of the two formulations of example 1 were tested for their performance, while a commercially available tin-free self-polishing antifouling paint was used as a control.
The antifouling performance dynamic simulation refers to GB/T7789-2007; the cathodic disbonding resistance test of the coating in seawater refers to GB/T7790-2008; the shallow sea soakability of the antifouling paint coating refers to GB/T5370-2007; the tap water soaking is to soak in tap water at 40 ℃ for 4 months to coat. The cathodic disbondment experiments of the antifouling paint 4200h after seawater immersion and 4200h after seawater immersion were carried out in accordance with norwegian norsosok M501.
And (3) performance detection results:
1. seawater standing soaking performance test
After being soaked in a certain sea area for 62 months, the result is shown in figure 1, the leftmost side of the sea area is a conventional control product, the adhesion of visible marine organisms is very serious, and the steel plate per se cannot be seen. The steel plates with the numbers 5542 and 5543 are coated with the antifouling paint, only a very small amount of small-volume marine organisms are attached after soaking, and the surface of the paint film is still smooth and complete.
2. And (3) dynamic simulation performance test:
the dynamic simulation test is to simulate the thickness of the coating thinning during service of the antifouling paint, and forms a relative rate in relation to time. Is an important index for inspecting antifouling performance.
Circumferential velocity in the test: 3-10 sections (1.54-5.14 m/s) of simulated circulating water pipeline flow velocity. Each period is 200h dynamic simulation experiment +1 month time of seawater immersion. For a total of 10 cycles.
Results referring to fig. 2, the control product coating film had developed a more severe blistering cracking phenomenon, while the coating films of nos. 5542 and 5543 were still smooth and flat.
Dynamic simulation experiment coating film consumption speed curve referring to fig. 3, the coating film consumption speed and service time of numbers 5542 and 5543 always show good linear relation, which shows that the coating film continuously plays an antifouling role in the service process.
3. Test of immersion property in 40 ℃ tap water
The coating films of numbers 5542 and 5543 have no cracking phenomenon after being soaked in tap water at 40 ℃ for 4 months, and the control products have severe cracking.
4. The cathodic disbondment test after 4200h seawater immersion of the epoxy primer (No. 5542) in the kit and 4200h seawater immersion was carried out according to norwegian NORSOK M501. The 20-year life cycle of the coating matched under the harsh maritime work condition in a natural state is verified through a 4200h simulation experiment. The simulation experiment proves that the matching of the epoxy primer coating completely meets the technical requirements of the standard M501.
